Husqvarna K 770 SmartGuard – Smarter Safety with Professional Power

The K 770 SmartGuard is a professional-grade gas powered concrete saw. It’s built for contractors who need strength, reliability, and safety in one machine. Based on the proven K 770 platform, this model includes Husqvarna’s exclusive SmartGuard extended blade guard. This guard helps operators maintain proper cutting technique while reducing the risk of kickback. From road repair to demolition and slab cutting, the K 770 SmartGuard delivers consistent performance with built-in protection.

SmartGuard Safety System for Safer Cutting

At the core of the K 770 SmartGuard is its extended blade guard. This innovative SmartGuard design reinforces safe operation by guiding the blade into the recommended cutting zone. This in-turn minimizes the chance of misaligned cuts or sudden kickbacks. Not only does it provide greater safety, but it also promotes better cutting habits. This makes it especially useful for both experienced crews and new operators.

  • Extended blade guard promotes correct technique
  • Safer operation with reduced kickback risk
  • Designed for tough, high-volume concrete cutting

Reliable Power with SmartTension™

Equipped with a 5 hp engine, the K 770 SmartGuard is engineered for strength and precision. Husqvarna’s semi-automatic SmartTension™ system ensures the drive belt maintains proper tension, which improves cutting performance, extends belt life, and reduces maintenance downtime. This combination of technology and power means more time cutting and less time adjusting.
